JDT problem. And I'm quite sure it is the same problem as bug 540738. *** This bug has been marked as a duplicate of bug 540738 *** |
Created attachment 279251 [details] Eclipse installation details Eclipse generates in internal compiler error (snapshot from the log) when it processes a java file with instruction "if (obj instanceof Object[]) {" !ENTRY org.eclipse.core.resources 4 75 2019-07-11 13:15:53.972 !MESSAGE Errors occurred during the build. !SUBENTRY 1 org.eclipse.jdt.core 4 75 2019-07-11 13:15:53.972 !MESSAGE Errors running builder 'Java Builder' on project 'xxxxxxxxxxxxxxxxx'. !STACK 0 java.lang.NullPointerException at java.base/java.lang.AbstractStringBuilder.append(AbstractStringBuilder.java:655) at java.base/java.lang.StringBuffer.append(StringBuffer.java:399) at org.eclipse.jdt.internal.compiler.lookup.ParameterizedTypeBinding.shortReadableName(ParameterizedTypeBinding.java:1267) at org.eclipse.jdt.internal.compiler.lookup.ParameterizedTypeBinding.shortReadableName(ParameterizedTypeBinding.java:1259) at org.eclipse.jdt.internal.compiler.problem.ProblemReporter.notCompatibleTypesErrorInForeach(ProblemReporter.java:7033) at org.eclipse.jdt.internal.compiler.ast.ForeachStatement.resolve(ForeachStatement.java:598) at org.eclipse.jdt.internal.compiler.ast.AbstractMethodDeclaration.resolveStatements(AbstractMethodDeclaration.java:641) at org.eclipse.jdt.internal.compiler.ast.MethodDeclaration.resolveStatements(MethodDeclaration.java:316) at org.eclipse.jdt.internal.compiler.ast.AbstractMethodDeclaration.resolve(AbstractMethodDeclaration.java:551) at org.eclipse.jdt.internal.compiler.ast.TypeDeclaration.resolve(TypeDeclaration.java:1262) at org.eclipse.jdt.internal.compiler.ast.TypeDeclaration.resolve(TypeDeclaration.java:1387) at org.eclipse.jdt.internal.compiler.ast.CompilationUnitDeclaration.resolve(CompilationUnitDeclaration.java:652) at org.eclipse.jdt.internal.compiler.Compiler.process(Compiler.java:892) at org.eclipse.jdt.internal.compiler.ProcessTaskManager.run(ProcessTaskManager.java:145) at java.base/java.lang.Thread.run(Thread.java:834) Replacing that line with "if (obj.getClass().isArray()) {" and clearing the project eliminates the internal compiler error. This error is reliably reproducible but only in one java module; I have the same line "if (obj instanceof Object[]) {" in a couple more modules and they don't seem to break the compiler.
